About this 3D model

These are now deprecated and replaced by version 2 - http://www.thingiverse.com/thing:469928 This converts a different sized fan (25mm thick) for use on an 80mm x 10mm fan connector. By doing this your noise level and sound level can be EXTREMELY decreased while putting out more CFM than an 80mm can do. There are extra tall versions (30mm taller) that allow more airflow to pass.
